1.6 - Metabolic Pathways Flashcards
Input of energy required to start a chemical reaction.
Activation energy
Region on an enzyme molecule where the substrate binds.
Active site
Metabolic pathways that consume energy in synthesis of complex molecules.
Anabolic
Metabolic pathway that releases energy in breakdown reactions.
Catabolic
Slowing of reaction rate due to the presence of a substrate resembling the substrate.
Competitive inhibition
Enzyme inhibition caused by the presence of an end product of a metabolic pathway.
Feedback inhibition
Change to an enzyme’s active site brought about by its substrate.
Induced fit
Enzyme-controlled sequence of chemical reactions in a cell.
Metabolic pathway
Enzyme inhibition by a substance that permanently alters the active site of the enzyme.
Non-competitive inhibition
Substance resulting from an enzyme-catalysed reaction.
Product
Molecule that brings about changes in a cell’s metabolism.
Signal molecule
Substance on which an enzyme works.
Substrate
